(D) An equipotential surface is defined as a surface where the electric potential is the same at every point.Therefore,the potential difference $(V_1 - V_2)$ between any two points on an equipotential surface is $0$.By the definition of electric potential,the work done $(W)$ in moving a charge $(q)$ from one point to another is given by $W = q(V_1 - V_2)$.Since $V_1 - V_2 = 0$,the work done $W = q 	imes 0 = 0$.Thus,no work is done in moving a unit positive charge over an equipotential surface.

If a unit positive charge is taken from one point to another over an equipotential surface,then
